pytorch获取当前GPU信息
pytorch获取当前GPU信息：
import torch
gpu_num = torch.cuda.device_count()
print('GPU数量：%d' % (gpu_num))
for i in range(gpu_num):
gpu_name = torch.cuda.get_device_name(i)
print('GPU名称：%s' % (gpu_name))
gpu_busy = torch.cuda.is_available()
print('%s是否可用：%d' % (gpu_name, gpu_busy))
gpu_index = torch.cuda.current_device()
print('当前GPU索引：%d' % (gpu_index))
